... Supernova explosion   in a binary is treated as an instantaneous mass loss of the exploding star. ... In this case, the eccentricity and semi-major axis of the binary after the explosion can be straightforwardly calculated (Boersma, 1961[ 21 ]). ... Then, the transition to a new system barycenter frame is made (at this point the spatial velocity of the new center of mass of the binary is computed), . ... During the CE stage, an effective spiral-in   of the binary components occurs. ...

... Advises . Contact Advises . As an advise for amateurs we would like to underline: if it's possible, try to observe 3 asteroid positions per night and do not neglect to observe the Numbered Minor Planets in your telescope field of view as a "by product" of your observational programs. ... We think such estimations ought to be produced every morning after CCD observations of the moving celestial objects by observer himself. ...
